A method is proposed for blocking inadmissible gearshift processes in a transmission with a plurality of shifting devices which, to carry out a shift process, are moved by actuating devices when a shift command is sent by a control unit (TCU) to the relevant actuating device. The actuating devices are connected for data exchange with one another and with the control unit (TCU) in such manner that the actuating device of the shifting device to be shifted is activated provided that clearance has been given by at least one other actuating device. In addition a shifting system is proposed for a transmission with a control unit and a plurality of actuating devices for the actuation of shifting devices, such that the actuating devices are associated with at least one shaft (A, B) and such that the actuating devices are connected for data exchange with one another and with the control unit (TCU) in such manner that the actuating device of the shifting device to be shifted can be activated provided that clearance has been given by at least one other actuating device.

Method for blocking inadmissible gear shifts in a transmission and shift assembly for a transmission

Method for operating an adjustable stabilizer arrangement including an actuator, which applies actuator torque to stabilizer sections as a function of a command variable to influence the rolling movement of a motor vehicle body, where sensors are used to detect the movement of the motor vehicle body and the movements of the wheels. An operating condition of the actuator supplies a variable which can be used to determine the actuator torque, upon which is superimposed an adjustment signal for the actuator, and where the variable is modified by a weighting factor.

The invention relates to a regulating mechanism for operating an actuator or connecting element () of an automatic transmission. The regulating mechanism has an actuator (), a regulating mechanism (), a transmission element (), and an output element (). According to the present invention, the actuator () is configured as a three phase motor, advantageously as an asynchronous motor. The torque (M) of the actuator () is converted into an actuating force (S) in the transmission element (), which is then applied to a regulated and or connecting element ().

A selector drive for automatic manual transmissions has an electric motor, the rotational motion of which can be transmitted to the selector mechanism for the selection of a selector position by way of a mechanical transmission chain. An electric motor () of the mechanical transmission chain is an electric motor with defined step width, whereby the required step number for the selection of the selector position in the selector mechanism can be determined through fixed geometrical conditions or distances according to the stipulations of the individual step angle of the electric motor and the distance between the selector positions.
